Multivariate, Multilevel Regression Model Showing Association of Clinician Use of Chronic Care Model Elements and 2 Measures of Process of Diabetes Care

Parameter	Parameter Estimate*	SE	P Value
Behavioral care composite score†
Intercept	1.7038	0.2891	<.001
Patient age	−0.0054	0.0029	.07
Patient race/ethnicity: white (vs nonwhite)	0.1483	0.0927	.11
Patient PHQ-9 (depression) score	−0.0130	0.0074	.08
Clinician score for use of CCM	0.2105	0.0595	.001
Clinical care composite score‡
Intercept	2.8214	0.3672	<.001
Patient age	0.0066	0.0031	.03
Patient race/ethnicity: white (vs nonwhite)	0.1418	0.0958	.14
Clinician score for use of CCM	0.1592	0.0868	.07

PHQ-9 = 9-item Patient Health Questionnaire; CCM = Chronic Care Model.

* The parameter estimates indicate the strength of the association in each model. Each unit difference in clinician-reported frequency of CCM use (eg, from “rarely” to “occasionally”) is associated with a change in the dependent variable (behavioral care composite score or clinical care composite score) equal to the parameter estimate.

† Covariates included patient age, race/ethnicity, and severity of depressive symptoms (PHQ-9 score).

‡ Covariates included patient age and race/ethnicity.
